extrude a grid between two surfaces

I am trying to extrude a grid between two surfaces, I tried to loft but for some reason i can't get it done on a straight line, they keep on intersecting at some weird points, I tried to pick the align loft option but no hopes, and its driving me crazy to get it done right.

I am trying to connect them straight to each other. I attached a sketch to show you what I am looking for.

nice one, tried it also rotated it and than flipped the uv but saw on the isocurves that the problem was anther just didnt knew about scaling by factor -1. is it some kind of flipping the seams direction. there is no command i assume? Did you get the arrows in GH?
